act description. v y '1 l The object of the invention is to provide certain new and vuseful improvements 1n 1nternal combustion eng1nes,ivliereby'the piston, the cylinder and the parte in the crank case can be-Yreedily oiled .Without danger of the lubricantpessing intotlie combustion bustion chamber B chamber and being'burne'dtherein. Forthe purpose mentioned use is Inadeof s Weterjeck'eted cylinder heed ryn'ovidnig e combustion chamber in the vsaid cylinder and spaced from the inner surface thereof to form` with the cylinder an annuler spece and u piston reciprocating in the seidcylinder and having a tubular extension passing .into the scid annular spacci A practical embodiment of theiinvention is represented in the acoompenyingdruiy ings forming a Jort of this specification, in which similar characters of reference indi- `cute corresponding parte in both viewsm Figure`1 isa sectional side elevation of the improvement; and Fig. 2 is a sectional plan View of the same on the line 4ci" Fi 1. f

iis shown in Fig, 1,the cylinder A of' the internul'combusticn engine Vis provided with n cylinder heed B huvingthe usual velvecontrolled Liinlets and outlets C and D for the entrange of the combustible mixture into ,the cylinder and the exhaustv of the burnedV gases from the cylinder.l The cylinder heed B is provided with a water-jncketed corno cylindrical form sind extending into the upper end of the cylinder A y'and spaced `from'the inner surface of the cylinder wull'to forni with the latter an annular space E. In the cylinder A below reciprocates l the piston F connected'by zi pitman G with the crank arm onthe main shaft of the engine, and the piston F is provided zit-itsupper end with u tubular extension F extending into the nnnulur, spuce E. The waiter- `jucketed combustionechamber B is provided exteriorly und neng-1 the lower `en d thereof with packing ringsiH 'engaging the inn'er surface of the tubulgtr extension F so as to forni o tight joint between the vcombustion no. inscri.

Choi/uber E" andthe ely/lindern. Thetlubuler extension F exceeds in length the stroke of the piston F so that ifhen the latter is in iowermost position the upper endI of the'g tubular extension F is still in engagement with the peickingiga rings4 H,- and when the piston F is in its uppermost position, as shown in Fig'. l, then the top of the tubular extension F is Within n short distenceof the top of the cylinder A, and the' parts in Patented i5,

the crunk casing-can be properly oiled with! i "ont danger of any oil working into the combustion chamber B, end consequently the lutter is kept ree from the deleterious ini.

uence of the lubricant. It is Well known that lnnicunt burning in the ,combustion chamber cakes therein and hence is liable to clog the working parts. it will further be noticed that by the arrangement described the cylinder jacket as the come directly in contact with it, ind the cylinder as Well as the piston can bel made comparatively light as the piston does not reuuirepacking rings. Haring thus described my invention, l' clsini es Potent:

L An internal combustion engine provided' with a cylinder7 e cylinder head provided with e cylindrical combustion cham` her open :it both ends und extending into the .said cylinder, the combustion chamber having mi integral water jacket surrounding the suine und extending from the top to the bottom of the combustion chamber, the scid water jacket being spaced from the cylinder wullto form an annular space be tween the seid water jacket of the 'combustion chamber and the cylinder, and a piston mounted to reciprocate in the suid cylinder below 'thc said Water jacketand the combustion chamber. and having u tubular ex-y tension pass-ingr into the said annular space. 2. AnV internal combustion engine provided-with u cylinder, a cylinder head provided with u combustion chamber of cylindrical fori-n open at both ends and extending into the said cylinder, the combustion chamber haring n Water jacket surrounding the sinnethroughout its length, and spaced from the cylinder wall to form an annuler space between the wzl-ter jacket of the coinbustiou chamber und the cylinder` e piston mounted to reciprocate in the said 4cylinder below the water jacket and the combustion new und desire to secure by Letters piston extension.

Vchamber and havin a tabular extension passing into the sald annular space, and packing-.rings held exteriorly on the said water jacket of the c'ornbustion chamber nearthe lower end thereof and in engagement with the innenface of the saidv tubglar upper end-of the cylinder and spaced 'from' the inner surface thereof to provide'an anl v nular 'space between vthejwater jacket ofv the combustion chamber and the cylinder, packing rings held exteriorly on the water jacket of the combustion chamber near the inner end thereof,` and a piston mounted to reciprocate inthe lsaid cylinderr` below the water jacketed combustion chamber' .and

having a` tubular extensionfof a length exceeding the stroke' of the piston, the said f tubular piston extension-extending into" the saidannular space and engaging the packingfrings, the said cylinderhead having a valvecontrolled inlet and a valve controlled outlet extending horizontally above the Water jacketed' combustion chamber and opening mto said head above the open top of the combustion chamber at'opposite sides thereof. -i

4 In an Ainternal combustion-engine, a cyllnder, a cylinder head provided with a de- 1,1 meer 'pendingy cylmdrical conibiistion chamber vopen at both endsl and-'extending into the,-

upper end .of the cylinder, a cylindrical water jackett surrounding the combustion water jacket and the combustion chamberv andhaving a tubular extension passin into 40 chamber and `spaced from the inner surface of the cylinder` wall to form with the latterzanannular space, a vpiston mountedto' reciprocate in the said cylinder below the the said annular space, the'saidcyinder head having a valve controlled inlet and a valve controlled outlet openinginto the cyl 3l inder head at opposite sides of the combus-v tion chamber above the open top thereof. c
